JESSE e. GROVE, or mm OAK, IOWA;

'Be known that l dnssn Gq Gnovn, a citizen of the United, States, residing at Red Oak, in the county of Montgomery and State of Iowa, have invented certain new and, useful Improvements ,in OilTcst lWrenches of which the following is a specificatlon.

The present invention relates to tools and more articularly to a device which' may be used or operating pet cocks and cleaning the same, 'i

The principal objectsof the invention are, to rovide a tool of the character described WhlChlS well adapted to open and close, and clean if necessary the ways of pet cocksused in connection with the oil sump of i Ford automobiles, without the necessity of the;

user'reaching under the automobile; to so shape an element of the tool that it may be readilyvdisposed into operative relation tothe handle of the pet cock and there retained during the opening and closing of the 'pet cock; and to providesuch tools with a handle and cleaner integral therewith, which is inexpensive to manufacture, light in Weight and durable.

Other objects and advantages of the invention will appear in the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings: Figure 1 is a side elevationof the tool,

Fig. 2 is an enlargedview of the tool in operative relation to a pet cock assuming that the tool has been given a quarter turn to open the pet cock, a portion of the handle being broken away to condense the view;

Fi 3 is a View similar to Fi 2 but'in' plan with the pet cock handle in open position. i

a Fig. 4 is ahorizontal sectional view through the pet cock showing the cleaner portion or ram ofthe tool in the way of the pet cock.

Fig. 5is a fragmentary view of a portion of the handle of the tool, showing the socket in cross section.

In the drawings where similar characters refer. to, similar parts throughout the views,

A designates a pet cock including a body portion B of any desired shape and a tapering plug C having a handle D, the body 13 and plug 6 having ways E and F respectively, adapted to be alined for the pasdesignates the wrench.

i OIL-TEST WRENCH.

sage of fluid through the Pet cocks, such as are illustrated in the oflicial drawings are used in connection with the oil sump on automobiles, and particularly Ford automobiles, to enable a person to determine whether or not thereis .suflicient lubricating oil in the sump, or to permit of the removal of some of the oil, if too great a quantity has been poured into the crank case. These pet cocks are apt to become clogged, however, due to dust and dirt entering the crank case through the ar.'s,;192 1.

pet cock; and G 7 breather tube. The oil sump being located beneath the body of the car in close'proximity to the longitudinal axis of the running gear, it is difiicult to reach these pet cocks without stooping down and reaching beneath the fender, and other parts of the body, of the vehicle. times it is necessary to resort to the use of a tool, such as pinccrs or pliers for turning the tapered member C, dueto, the fact that these pet cocks are exposed to moisture and; dirt of theroad, and stooping, in the manner above set forth, a person may successfully open the pet cocks, but if it has a tendency to stick, the

tool usedmay slip from the handle D and too great a quantity of lubricating oil will pass out before a good hold may again be gained, thus resultlng in the Waste of lubricant. If clogged with sediment, a match or' SIIIllliLl element is sometnnes used to push' the same from obstructing the ways E and F, but when such element is withdrawn and the oil flows out of thepet cook, the hand 1 holding the element is very apt to become oily, making it difficult to close the pet cock relatively short stem 9 in angular relation thereto, at one end, the said stem preferably being rounded as at 10. Thls short stem 9 aids in impartlng a circumferential movement to the handle, and may also serve as a ram for cleaning the bore or ways E and F of the pet cock, without the necessity of the user reaching beneath the body of the vehicle.

The socket 7 may be cheaply and conveniently formed of sheet metal and in the preferred embodiment is provided with a perforation 11 intermediate its ends, of a size substantially the diameter of the wire handle 6. The sheet of metal, properly shaped, and while flat, as indicated by dotted lines 12 in Fig. 5, may then be slipped upon the end portion of the long stem 8, opposite to short stem 9, and then bent to U-shape, as shown by full lines in Fig. 5. In so doing metal of the socket 7, bounding the perforation ll, bites into the wire handle 6 at opposite ortions thereof, as indicated at 13, and tliereby fixes the socket to the handle so as to turn with it, when a turning movement is imparted to the handle. The end portion of the handle 6 may be upset, slightly, as indicated at 14 to more securely attach the socket to the handle. This is a sim le and efiicient manner of attachment of t e socket to the handle. The end portions of the Ushaped socket are preferably flared outward] as indicated at 15 to facilitate guiding o the sockets into operative relation to the handle D. If desired, the socket may be made of slightly resilient material, and the portions 16 extending from the handle normally spaced a distance which is slightly less than the width of handle D, so that slight forward pressure longitudinally of the handle must be applied in order to disppse it into operative relation to the handle after which a turning movement may be imparted to the handle, as through the oil"- set short stem 9.

If, after opening the pet cocks, there is no flow, or a weak flow of oil therefrom, the short stem 9 ma be forced through the alined ways E and l and when withdrawn, will permit some of the oil escaping to carry oil the sediment, after which the socket 7 being bent to rovide a relatively long stem. and a relative y short stem in angular rela tion thereto at one end, said short stem being adapted to act as a ram in the bore the pet cock, and a socket member of shaped formation at the other end of said.

relatively long stem of the handle for engagement with the handle of the pet cock.

An oil test wrench comprising in combination a wire handle and a socket formed of a sheet of material provided with a perforation intermediate 1ts ends, the end of the wire handle extending through said perforation and the sheet of material being bent to U-shape with its base curved and a portion of the material bounding the perforation biting into the wire handle at 0pposite portions thereof to cause the socket to turn with the handle when a turning movement is impag ted to the latter- JES G O E
